In 1282, the coins struck by the Royal Mint were independently and rigorously checked to determine their quality and fineness, it is known as the Trial of the Pyx and today over 700 years later, it still takes place. Every year an independent jury, sworn in by the Queen’s Remembrancer, ascertains whether the coins made by the Royal Mint are of the correct weight, diameter and composition required by law. This means you can rest assured that the coin or coins in your possession are of the highest quality.
